IMPROVEMENT IN HORSE HAY-FORKS.

The Schedule referred to in these Letters Patent and making peut of the same.

Be it known that I, JOSEPH dnxxrxes, of Jacksonprinciple being the same', whether four or any other number are used.

The inside lifting-chains c c e c may be chains or ropes, being attached at one end upon the inside of the teeth b b b b, and passing under the frame c, the opposite ends being attached to rings, into one of which rings have invented a new, useful, and improved Horse Hay-Fork, for handling hay, grain, and other substances by'horse-power; and I do hereby declarethe following to be a full, clear, and exact. description ot' the construction and operation of the same, reference being had to the annexed drawings, making a part of rope y is pulled. The outside lifting-chains d. d l d are attached to the teeth b b b b, upon the outside ofthe frame a, and passing up upon the outside of said frame,--are fastened to the collar k at the opposite end. Having described a suiiicient number of parts to give an 4idea of the whole, in connection with the. drawings, the operation will be as follows:

Let it be supposed that the fork has its load grappled, as shown in fig. l, and is suspended over the stack by the derrick and supporting-rope h, and that the 0perator desires to unload the fork upon the stack. To unload, he simply gives a jerk to the connecting-rope y', attached to the long end of the lever-hook f, and the ring E slips oii' from the hook f, thus loosening the inside lifting-chains c c c c, and the weight of the machine and its load instantly comes upon the outside chains al d l d, thus opening the teeth and dropping out the load, and placing the fork in the position shown in the drawings, iig. 2.

rlhe fork is then dropped, in its open position, as shown in iig. 2, down upon the hay"` to grapple another load. Then it rests upon the hay, the outside chains slacken up, the lever-hook j' going clear down upon the hay, and the operator gives a jerk to the rope g, which draws the ring E into the hook f, and the fork is at once drawn up by the rope It, and as it rises itfgrapples its load, and instantly assumes the position shown this specitication, in which- Figure lis a view of the lmachine with its load grappled.

A careful inspection of the drawings will give a beteial terms, the construction is as follows, so far as its substantial parts are concerned:

the stack and unloaded as before described.

What I claim as new, and desireto secure by Letters Patent, is

l. The lever-hook f, in connection with the rod t and lthe ropes gand g', attached to oppositel ends of the lever-hook, as set forth and described.

oblong or square, as convenience dictates, the principle of hooking and unhooking the inside and outside connecting-chains being the same, whatever the form of the frame may be.

. The teeth or tines b b b b are nearly semicircular in form, fastened to the frame at one en d by a jointor pivot, so asto swing up and down upon said joint, and are closed, so as tograpple their load, by the draught upon the inside connecting-chainsc c c c, andare opened, so as to unload, -.by the draught upon the outside connectinghook f, chains c and (l, and tines b, arranged and operating substantially as described.
